We have calculated the band structure and dielectric function of InP b
y means of an accurate first-principles method using the full potentia
l linear muffin-tin orbital method (FPLMTO). Our calculated dielectric
functions is compared with the recent data of Herzinger et al. [J. Ap
pl. Phys., 77, 1995, 1715]. The calculated dielectric function is in g
ood agreement with the recent data. The calculated band gap is smaller
by about 0.7 eV in comparison with experimental gap. (C) 1997 Elsevie
